Description

  The present invention relates to a masking composition, and more particularly, a composition containing citronellal, propylene glycol dicaprate, a specific monoester, a monohydric alcohol having 1 to 3 carbon atoms, and paramethoxycinnamic acid It has the characteristic which is excellent in the effect which masks the bad smell of 2-ethylhexyl.

  Cosmetics are expected to have various effects and contain various components. Of these, 2-ethylhexyl paramethoxycinnamate is widely used in sunscreens and the like as an ultraviolet protection agent, but may be hydrolyzed due to other components contained therein, the influence of aging, and the like. 2-Ethylhexanol produced by this hydrolysis has a strong unpleasant odor, and is a factor that significantly lowers its value particularly in preparations used for the human body such as cosmetics. Usually, it is possible to obscure a certain level of odor by including a fragrance component in cosmetics, etc., but since a significant unpleasant odor is caused by the level of hydrolysis, a technique for masking is required. come.

  In general, for such unpleasant odor, a masking method is used to make the unpleasant odor less felt by coexisting a fragrance component with a higher strength, but as a result, the odor becomes stronger and in cosmetics etc. It may lead to a decrease in the feeling of use. So far, many studies have been made on components that can effectively mask unpleasant odors (see, for example, Patent Documents 1 and 2). In addition, unpleasant odor varies depending on the structure of the components that cause it, and it is difficult to uniformly mask it, and therefore, a masking method corresponding to the cause of unpleasant odor has also been reported (for example, Patent Documents 3 and 4). reference).

Japanese Patent Laid-Open No. 6-158096 JP 2002-3329 A JP 2002-47127 A JP-A-2005-170860

  As described above, the unpleasant odor varies depending on the structure of the component that is a factor, and it is difficult to mask it uniformly. In addition, in the prior art, it has been difficult to sufficiently mask the unpleasant odor of 2-ethylhexanol produced by hydrolysis of 2-ethylhexyl paramethoxycinnamate. Therefore, the problem to be solved by the present invention is to provide a composition for masking the unpleasant odor of 2-ethylhexanol produced by hydrolysis of 2-ethylhexyl paramethoxycinnamate which is useful in cosmetics. .

  In view of such a situation, the present inventor has intensively studied to solve the above problems, and as a result, has found that citronellal has a high masking effect against the deodorization of 2-ethylhexyl paramethoxycinnamate. Essential oils containing citronellal and the like have been conventionally known as masking agents, but when applied to cosmetics and the like, an unpleasant odor may be enhanced by the inclusion of many other ingredients. We thought that technology to further enhance the masking effect was necessary. In addition, for this purpose, it was thought that a state in which 2-ethylhexanol, which is a cause of odor, was mixed with citronellal and that could exhibit an effect as a masking composition was necessary. Based on these conditions, a number of cosmetic ingredients were examined, and by combining propylene glycol dicaprate, specific ester oils, and monohydric alcohols, the masking effect that cannot be obtained with citronellal alone was improved. The heading and the masking composition of the present invention were completed.
